DETAILED DESCRIPTION OF THE INVENTION

1. Regimen

[0008] The present invention relates to a method of treating skin
comprising various steps but where at least one of said steps involves
contact skin with a composition comprising a pyrithione source, such as
zinc pyrithione.

[0009] In one embodiment, the invention relates to a method of treating
skin comprising: applying a first composition to a portion of skin to
form a prepared surface; contacting said prepared surface with a hair
removal device to form a contacted surface, wherein said hair removal
device comprises at least one skin engaging member, at least one molded
shaving aid, and a combination thereof; applying a second composition to
said contacted surface to form a treated surface, wherein at least one of
said first composition, said at least one skin engaging member, said at
least one molded shaving aid, and said second composition comprises a
pyrithione source. In one embodiment, the pyrithione source is selected
from a group consisting of zinc pyrithione, sodium pyrithione, pyrithione
acid, dipyrithione, chitonsan pyrithione, magnesium disulfide pyrithione,
and combinations thereof. The pyrithione source can be at varying levels,
such as at a level of from about 0.01% to about 5%, by weight of said
composition wherein it is present (for example if the pyrithione source
is present in the first or second composition, or where it is present in
a shaving aid).

[0010] In one embodiment, said pyrithione source comprises a platelet zinc
pyrithione (platelet ZPT), wherein the platelet ZPT comprises a mean
particle diameter of about 0.5 microns to about 10 microns, a median
particle diameter of about 0.5 microns to about 10 microns, and a
thickness of about 0.6 microns to about 15 microns. The mean particle
diameter of the platelet ZPT can be about 1 micron to about 5 microns.
The median particle diameter of the platelet ZPT can be about 0.6 microns
to about 0.7 microns.

[0011] In one embodiment, more than one of said first composition, said at
least one skin engaging member, said at least one molded shaving aid, and
said second composition comprises a pyrithione source. For example, the
pyrithione source can provide different benefits depending where it is
present. Without intending to be bound by theory, it is believed that if
it is present in the first composition, which can be a pre-shaving
preparation such as a post foaming shave gel or foam, or a pre-shave oil
or other pre-treatment composition (which can be used even before the
shave preparation / first composition), the pyrithione source can provide
anti-irritation benefits. If it is present as part of the hair removal
device or razor, the pyrithione source can provide anti-irritation and/or
anti-bacterial benefits. When it is present in the second composition, it
is believed that the pyrithione source can provide anti-bacterial
benefits which may last after the hair removal process. This can be
particularly useful for underarm or private area hair removal. In one
embodiment, pyrithione is present in one or more molded shaving aids
present on the cartridge and the second composition.

[0012] In one embodiment, the user can be instructed to rinse following
the hair removal step and prior to the step of applying the second
composition. The second composition can also be a rinse off composition
such as a facial wash or in shower moisturizer but can be a leave on,
such as a lotion or moisturizer.

2. Pyrithione Source

[0013] As used herein, the pyrithione source can be a pyrithione and a
pyrithione salt capable of providing antimicrobial efficacy and/ or
anti-irritation on skin when the pyrithione source is used in a shave
preparation composition. Preferred pyrithione salts are those formed from
heavy metals such as zinc, tin, cadmium, magnesium, aluminum and
zirconium. Zinc salts are most preferred, especially the zinc salt of
1-hydroxy-2-pyridinethione (zinc pyridinethione, also named zinc
pyrithione, ZPT). Other cations such as sodium may also be suitable. The
pyrithione source may be selected from the group consisting of sodium
pyrithione, zinc pyrithione, magnesium disulfide pyrithione, pyrithione
acid, dipyrithione, chitosan pyrithione and combinations thereof.
Preferably, it is sodium pyrithione or zinc pyrithione and more
preferably, it is a zinc pyrithione (ZPT). ZPT is commercially available
from various suppliers. For example, ZPT FPS available from Arch Chemical
can be used. It is an aqueous dispersion comprising 48% active ZPT.
Pyrithione sources are well known in the personal cleansing art, and are
described, for example, in U.S. Pat. No. 2,809,971; U.S. Pat. No.
3,236,733; U.S. Pat. No. 3,753,196; U.S. Pat. No. 3,761,418; U.S. Pat.
No. 4,345,080; U.S. Pat. No. 4,323,683; U.S. Pat. No. 4,379,753; and U.S.
Pat. No. 4,470,982. Descriptions about pyrithione sources in the above
mentioned patents are incorporated herein by reference. The pyrithione
source can be present in the present composition in an amount ranging
from about 0.05%, 0.1% or 0.4% to about 0.5%, 2% or 5%.

3. Zinc Source

[0014] The present composition may additionally comprise a zinc source.
Suitable zinc source include those zinc-containing materials described in
U.S. Pat. No. 4,161,526, which can also provide discoloration inhibiting
benefit. Specifically, the zinc source is selected from a group
consisting of a zinc salt of an organic carboxylic zinc salt, inorganic
zinc salt, zinc hydroxide, zinc oxide, and combinations thereof. In one
embodiment, the zinc source is zinc carbonate and/or zinc oxide. The zinc
source, for example, zinc carbonate is also known as being able to
potentiate the efficacy of the pyrithione source. The present composition
comprises from 0.01% to 0.5% of a zinc source. In one embodiment of the
present invention, the present soap base comprises 0.5% zinc pyrithione,
2% sodium carbonate, and 0.1% zinc carbonate.

4. Zinc Pyrithione

[0015] According to an example embodiment, the composition can further
comprise a pyrithione or a polyvalent metal salt of pyrithione such as a
zinc salt of 1-hydroxy-2-pyridinethione (known as "zinc pyrithione" or
"ZPT").

[0016] In a preferred embodiment, the zinc pyrithione included in soap
base is dry powder zinc pyrithione in platelet particle form ("platelet
ZPT"). According to example embodiments, the platelet ZPT included in the
soap base composition can include particles with, for example, a median
particle diameter of about 0.5 microns to about 10, alternatively about 1
to about 5 microns, and alternatively about 3 microns and a mean particle
diameter of about 0.5 to about 10 microns, alternatively about 1 to about
5 microns, alternatively about 2 to about 4 microns, and alternatively
about 3 microns. The platelet ZPT can also have a thickness of about 0.6
to about 15 microns, alternatively about 0.6 to about 1 micron,
alternatively about 0.6 microns to about 0.8 microns, and alternatively
about 0.6 microns to about 0.7 microns as shown in FIG. 1. The platelet
ZPT included in the antimicrobial bar composition can also have a span of
less than about 5, and alternatively about 1.

[0017] The antimicrobial bar composition can include from about 0.01% to
about 5%, by weight of the bar composition, of platelet ZPT,
alternatively from about 0.1% to about 2%, and alternatively from about
0.1% to about 1%.

[0018] According to an example embodiment, the platelet ZPT can be
included in the antimicrobial bar compositions disclosed herein as a dry
power that is, for example, dispersed with the soap. Alternatively, the
platelet ZPT can be included in the antimicrobial bar compositions
disclosed herein as aqueous dispersion with, for example, the soap.

[0019] The platelet ZPT included in the antimicrobial bar composition can
be stabilized against, for example, flocculation. In one embodiment, each
of the platelet ZPTs used in the antimicrobial bar composition can have a
coating or layer thereon to prevent the platelet ZPTs from attaching to
each other. The coating or layer can be polynaphthalene sulfonate or any
other suitable sulfate, sulfonate, carboxylate, or other compound that
provides stability for example by charge or steric barrier.

[0020] In example embodiments, the ZPT can be made by reacting
1-hydroxy-2-pyridinethione (i.e., pyrithione acid) or a soluble salt
thereof with a zinc salt (e.g. zinc sulfate) to form a zinc pyrithione
precipitate as illustrated in U.S. Pat. No. 2,809,971 and the zinc
pyrithione can be formed or processed into platelet ZPT using, for
example, sonic energy as illustrated in U.S. Pat. No. 6,682,724.

[0021] It has been discovered that the use of platelet ZPT in an soap base
such as the antimicrobial bar composition disclosed herein provides
improvements in the efficiency of the amount of ZPT deposited on the
surface upon which the antimicrobial bar composition is being used on as
well as reductions in the amount of antimicrobials that form after use.
More specifically, it has been discovered that the use of platelet ZPT
having a median particle diameter of about 1 micron to about 5 microns, a
mean particle diameter of about 1 microns to about 5 microns, and a
thickness of about 0.6 microns to about 15 microns in an antimicrobial
bar composition such as the antimicrobial bar composition disclosed
herein provides improvements in the efficiency of the amount of ZPT
deposited on the surface upon which the antimicrobial bar composition is
being used on as well as reductions in the amount of antimicrobials that
form after use in comparison with, for example, particulate ZPT such as
the particulate ZPT shown in FIG. 2. FIG. 3 illustrates these
improvements by comparing an antimicrobial bar composition that includes
particulate ZPT having a median particle diameter of about 0.70 microns,
a mean particle diameter of about 0.75 microns, and a thickness of less
than 0.6 microns with an antimicrobial bar composition that includes
platelet ZPT described above. As shown in FIG. 1, the use of platelet ZPT
reduces the number of colony forming units (CFUs) that form on a
substrate in comparison with particulate ZPT. As such, the use of
platelet ZPT increases the residual efficacy of the antimicrobial bar
composition and provides protection on the surface the antimicrobial bar
composition is used on from subsequent invasions of microbials.

5. Additional Antibacterial Agents

[0022] The composition containing the pyrithione source can optionally
further include one or more additional antibacterial agents that can
serve to further enhance the antimicrobial effectiveness of the bar
compositions. When present, the antimicrobial bar composition can include
from about 0.001% to about 2%, preferably from about 0.01% to about 1.5%,
more preferably from about 0.1% to about 1%, by weight of the
antimicrobial bar composition. Examples of antibacterial agents that can
be employed are the carbanilides, for example, triclocarban (also known
as trichlorocarbanilide), triclosan, a halogenated diphenylether
available as DP-300 from Ciba-Geigy, hexachlorophene,
3,4,5-tribromosalicylanilide, and salts of 2-pyridinethiol-1-oxide,
salicylic acid and other organic acids. Other suitable antibacterial
agents are described in detail in U.S. Pat. No. 6,488,943 (referred to as
antimicrobial actives).

6. First Composition

[0023] The first composition can be many different types of compositions
which can be used in a pre-hair removal context. Non-limiting examples
include shave foams, post foaming shave gels, non-aerosol shave gels,
personal cleansers, shave oils, and even liquid or bar soaps.
Non-limiting examples of first compositions comprising a pyrithione
source is available in:

fluid to be dispensed during use of the hair removal device, the hair
removal device additionally comprising a rigid container enclosing the
collapsible reservoir, a fluid outlet adapted to allow fluid to exit both
the collapsible reservoir and the rigid container, a first one-way valve
adapted to allow air to enter but not exit the rigid container, and a
pressure applicator, adapted to pressurize air in the rigid container,
thereby collapsing the collapsible reservoir and causing fluid to be
expelled through fluid outlet.

[0036] In one embodiment, the composition dispensing razor is as described
in U.S. Patent Publ. No. 2010/0095529A1 disclosing a hair removal device
comprising a handle and a collapsible reservoir suitable for containing a
fluid to be dispensed during use of the hair removal device, the hair
removal device additionally comprising a rigid container enclosing the
collapsible reservoir, a fluid outlet adapted to allow fluid to exit both
the collapsible reservoir and the rigid container, an orifice adapted to
allow air to flow in or out of the rigid container, and a suction device
(such as a power or manual pump), adapted to suck fluid out of the
collapsible reservoir through fluid outlet.

[0037] US Patent Pub. No 2006/0150386A1 teaches another suitable
composition dispensing razor which can be used in accordance with the
present invention. According to this patent application, a razor is
taught in which a flexible bladder comprising shaving agent is located
within the handle. Dispensing takes place by squeezing flexible regions
of the handle which act directly on the bladder to compress it and expel
shaving composition contained therein.

[0038] Additional non-limiting examples of composition dispensing dry
shavers have been disclosed in U.S. Patent Publ. No. 2008/0216322 and
RE038934. For example, the hair removal device can be similar to the
Phillips Norelco composition dispensing razor under the name of Cool Skin
Shaver®. The shaver can have a large main head containing multiple
rotary blades and dispenses a various types of moisturizing shave lotions
out of the center of the rotary blades, allowing the composition to coat
the shaving head and cutters to allegedly decrease friction with skin.

[0039] Other suitable dispensing wet razors have been disclosed in: U.S.
Patents Publications 2006/00240380 to Chenvainu et al; 2007/0084074 to
Szczepanowski et al; 2008/0307653A1 to Wattam (with a dispensing point at
or near the pivot point of the cartridge), 2010/0236071A1 or
2010/0236072A1, and U.S. Pat. Nos. 7,127,817; 7,121,754; and 6,789,321,
U.S. Patent Publ. Nos. 2011/0219621A1 and 2012/0102750A1. Other attempts
to dispense fluids out of razors include devices with product dispense
ports dispensing directly out of some portion of the razor handle for a
two hand operation during use. See, e.g., U.S. Pat. Nos. 5,701,674, and
5,070,611 as well as in U.S. Patent Publ. No. 2012/0103928A1 (disclosing
a personal care bottle with a first end wall and a second end wall
opposite the first end wall. The second end wall defines an aperture. The
personal care bottle has a top surface and an opposing bottom surface
connecting the first and second end walls. The bottom surface has a wall
thickness that is less than a wall thickness of the top surface), and
U.S. Pat. No. 8,220,156 (disclosing A hair removal kit having a handle, a
cover removably engagable to the handle, and a cartridge removably
engagable to the handle. The cartridge has at least one blade. A
removable dispensing unit is disposed within the handle. The dispensing
unit has a pump, an applicator in liquid communication with the pump, and
a reservoir having a first position and a second position. The reservoir
is in liquid communication with the pump in the second position, but not
in liquid communication with the pump in the first position).

[0040] In one embodiment, the first composition can be contained in a
compartment or reservoir formed in the composition dispensing razor and
can be dispense onto skin from said compartment or reservoir via a fluid
flow path onto the skin. In one embodiment, the step of dispensing the
first composition and the step of contacting said prepared surface happen
concurrently during a shaving stroke. The composition can be dispensed
forward of the razor cartridge or at or near the pivot point of the
cartridge, or aft of the cartridge so composition is dispensed after the
shave stroke. In one embodiment, the second composition can be supplied
by a compartment or reservoir provided along with said razor, such as in
a bottle for a post shave moisturizer.

[0041] All percentages disclosed herein, unless otherwise stated, are by
weight of the named material itself that is found in the compositions,
thereby excluding for example the weight associated with carriers,
impurities and by-products found in the raw material.

[0042] It should be understood that every maximum numerical limitation
given throughout this specification includes every lower numerical
limitation, as if such lower numerical limitations were expressly written
herein. Every minimum numerical limitation given throughout this
specification includes every higher numerical limitation, as if such
higher numerical limitations were expressly written herein. Every
numerical range given throughout this specification includes every
narrower numerical range that falls within such broader numerical range,
as if such narrower numerical ranges were all expressly written herein.

[0043] All parts, ratios, and percentages herein, in the Specification,
Examples, and Claims, are by weight and all numerical limits are used
with the normal degree of accuracy afforded by the art, unless otherwise
specified. The dimensions and values disclosed herein are not to be
understood as being strictly limited to the exact numerical values
recited. Instead, unless otherwise specified, each such dimension is
intended to mean both the recited value and a functionally equivalent
range surrounding that value. For example, a dimension disclosed as "40
mm" is intended to mean "about 40 mm".
